Thanks for the reply docbud! I think the problem with my basement (may be more of a cellar) is that half of it sticks out of the ground. So in the summer it is so hot and humid down there, in winter it is very cold. Your right though it holds in whatever there is. If it gets cold for a week the cellar gets cold and stays cold for about 5 days after regardless the temp outside. I also have landlords that do a lot of gardening outside, the vent for the cellar is about knee high/thigh high and they would be able to hear my ventilation equipment without a doubt. So I'm trying to avoid moving down there. Then again my currentlower cab. is only 18"x18"x5'10". This makes it very hard to find a fixture that will hang in there. I bought the shortest cooltube I could find but I still need to have the pyrex cut down a bit. As you know its get hot in that little cabinet per the reason for a cool tube. I only have and can only fit my one 250 watt HPS in there. How would you deal with the environment in a cellar/basement? there is no heat/air in there I guess I would need to buy a portable heater and a/c unit/ and a dehumidifier? Thanks for your reply doc!
A 250w in the basement should be fine. The big concrete heat sinks will spread that heat around it won't change the temps a bit. You may fight humidity issues though as you said. I need to get a new dehumidifier for the basement. I am running a bit high and these buds are dense!
